Abstract (en)
[origin: EP0502807A2] The present invention employs a pipe (2) of an insulating material, which can be inserted in an existing pipe system. A cable structure is wound on the pipe (2), whereby it is possible to indicate the conductance of the passing fluid on the basis of the characteristic impedance of the cable structure. As the pipe and the passing fluid form part of the cable structure, the characteristic impedance is dependent on the conductance of said passing fluid. <IMAGE>
